Step right up, and get your hands on a bottle of ferrofluid of your very own!

What is ferrofluid? Ferrofluid is a suspension of nano-sized iron particles suspended with a coating to prevent them from clumping together, forming a magnetic liquid that is easily controlled with a simple household magnet.

It responds to magnetic fields to produce unique patterns, shapes, and unusual behaviors, demonstrating properties of cohesion, density, magnetism, momentum, gravity, and polarity. It clusters, spikes, and dances in your hands, and makes for quite possibly the best idle desktop toy ever. Dazzle your friends! Astound your children! Bewilder your cat! It's science in a bottle.

Includes a 60mL bottle and one column magnet to play with.

**This is not a toy - caution is advised when handling it. Do not ingest, feed to Earth-based life forms, open bottle and allow to mutate, or remove from its container, and do not expose to extreme temperatures**
